Agentic AI

AI systems that can autonomously plan, use tools, and execute multi-step tasks with minimal human supervision, going beyond simple question-answering.

Explained at five levels

Level 1

AI that can do things on its own — like a robot helper that can look stuff up, use tools, and finish tasks without you telling it every step.

Level 2

AI that doesn't just answer questions but can actually take actions — browsing the web, writing code, sending emails — working like an assistant.

Level 3

AI systems that can autonomously plan, use tools, and execute multi-step tasks with minimal human supervision, going beyond simple question-answering.

Level 4

Autonomous or semi-autonomous AI systems that decompose goals into sub-tasks, invoke external tools and APIs, maintain working memory, and iteratively refine their approach based on environmental feedback.

Level 5

Systems exhibiting goal-directed behavior through recursive planning, tool invocation, and environmental interaction — implemented via ReAct-style reasoning loops, function calling, and hierarchical task decomposition with verifiable sub-goal completion.
